Not in my experience, but then those parsers might be incorrect... I see
two statements that could be seen as conflicting:

In the XML spec:

  The Namespaces in XML Recommendation [XML Names] assigns a meaning to
  names containing colon characters. Therefore, authors should not use the
  colon in XML names except for namespace purposes, but XML processors
  must accept the colon as a name character.

So assuming there is no foo prefix in scope in the above, the processor
must accept the colon anyway?

But then in the namespaces spec:

  The Prefix provides the namespace prefix part of the qualified name, and
  must be associated with a namespace URI reference in a namespace

Two possibly conflicting uses of "must" ?

Expat and Gnome's libxml both accept the above document, FWIW.
